摘要: 随着物联网技术的发展，RFID (无线射频识别)技术在室内定位领域得到了广泛应用。RFID技术凭借其低成本、部署简便和鲁棒性强等特点，成为解决室内定位难题的有效方案。本文综述了基于RFID的室内定位方法，首先介绍了室内定位技术的需求和挑战，分析了几种主流室内定位技术，并重点探讨了RFID技术的优势。接着，详细讨论了RFID定位的主要方法，包括基于信号到达时间(TOA)、到达时间差(TDOA)、到达角度(AOA)、接收信号强度(RSSI)和相位信息的定位方法。最后，本文展望了RFID室内定位技术的发展趋势，主要包括精度提升和多技术融合的趋势，以及稳定性和智能化发展的方向。随着技术的不断进步，RFID室内定位将在多个行业中发挥更大的作用。
Abstract: With the development of IoT technology, RFID technology has been widely applied in indoor positioning. Due to its low cost, easy deployment, and strong robustness, RFID has become an effective solution to the challenges of indoor positioning. This paper reviews RFID-based indoor positioning methods, first introducing the requirements and challenges of indoor positioning technology, analyzing several mainstream indoor positioning technologies, and focusing on the advantages of RFID technology. It then discusses the main RFID positioning methods in detail, including methods based on Time of Arrival (TOA), Time Difference of Arrival (TDOA), Angle of Arrival (AOA), Received Signal Strength Indicator (RSSI), and phase information. Finally, the paper looks forward to the development trends of RFID indoor positioning technology, mainly including the improvement of positioning accuracy and the trend of multi-technology integration, as well as the direction of stability and intelligent development. With continuous technological advancements, RFID indoor positioning will play a larger role in various industries.
